Abstract
Abstract A steerable surfing body board for use by a surfer to a hydroplane down the front face of a wave. Two rudders are mounted near the front of the board and two skags are mounted at the rear. A control handle on the upper surface operates the rudders in parallel through a cogged belt between the rudder axles in the center of the board. The handle is offset 45° from the position of the rudders placing the straight ahead position of the rudders in the center of the natural arc of the hand when the elbow rests on the upper surface of the board.

Claim 1
Independent Claim
118 words
A steerable hydroplaning body board, comprising: a body board having upper and lower surfaces and adapted to supporting a user on said upper surface; two rudders mounted on said lower surface; two skags mounted on said lower surface; and a control means mounted on said upper surface controlling said two rudders having: a single control handle for controlling both of said two rudders and maintaining said two rudders substantially parallel to each other; a separate axle for each of said two rubbers passing into said body board substantially perpendicular to said lower surface and parallel to each other; a pulley on each of said separate axles between said upper and lower surfaces; and a belt between said pulleys.
Claim 2
Dependent Claim
